Where is this coming from? People have “heard” of these things - “tamper fuses” etc. I suspect if there was any REAL proof it would be documented rather then just heresay... From what I have seen with my own two eyes, the digital technician used simply reads the calibration ID from the ECM. Plain and simple. Of course if you leave an aftermarket tune in place when the dealer plugs in, then of course your cooked. However you’d have to be pretty stupid to do that.

Now, who knows if HD can do a forensic analysis of your ECM if it was sent to corporate, but for the number of warrantiy claims they process on a daily basis, how often do you think that will happen. Guaranteed that will cost more time and effort then just approving the claim.

But as is all this speculation, other then what I observed personally, this is another case of one man’s opinion.

I went with the Street Cannons. I’m totally satisfied with the look and the sound. I didn’t want anything really loud and the SCs aren’t.
